Iphone 5 keeps switching to silent on its own
My Iphone 5 is stuck on silent mode, or more accurately it keeps switching to silent on its own.
The problem started about 2 days ago, after upgrading to iOS 7.1 last week. The phone keeps switching in and out of silent mode (without the button being touched) and mostly stays in silent. It's not a speaker problem, nor a settings problem, as I’ve checked every bit of online advice I could find. I tried restarting, resetting, restoring, cleaning the headphone jack, and nothing helps.
An attempt to see if it’s a headphone related issue (by plugging and unplugging while restarting in various combinations) got it working fine for about 5 minutes, then it switched back to silent.
Needless to say, the phone did not suffer from any physical damage prior to the problem.
